  • Thermosets from water-extended polyetherester emulsions
    Patent number: 5633315
    Abstract: Stable emulsions based on unsaturated polyetherester resins are disclosed. The emulsions have high stability compared with conventional emulsions that are based on unsaturated polyester resins. The invention includes base-stabilized emulsions, as well as emulsions containing fillers or functional additives. The emulsions, which are storage stable for weeks or months, are useful for making water-extended polyetherester thermosets having excellent physical properties, even at high water contents.
    Type: Grant
    Filed: May 8, 1995
    Date of Patent: May 27, 1997
    Assignee: ARCO Chemical Technology, L.P.
    Inventors: Gangfeng Cai, Shau-Hua Guo, Lau S. Yang
